Systems and techniques to provide radio frequency identification tags
including a non-responsive state, which is independent of supplied power,
initiated in conjunction with a tag communications reset. In general, in
one implementation, a passive radio frequency identification tag includes
an antenna, a radio frequency interface coupled with the antenna, and
control logic that initiates a deep sleep state in response an event, the
deep sleep state including a non-responsive state that is independent of
supplied power, and the control logic providing a following state entered
upon conclusion of the non-responsive state, where communications
initiate from the following state.
